SPEGEFICATION forming part of Letters Patent No. 344,588, dated .Tune-29, 1886.

Application filed May 4, 1886. Serial No. 201,088. (No model.)

.To a/ZZ wtom it may concern:

Beit known that I, JnMns D. MoDoUeAL, of Columbus, county of Franklin, State of Ohio, have invented new and useful Improvements in Flanging-Tools, of which the following is a full and exact `description, reference vbeing had to the accompanying drawings, making part of this specification.

My invention relates to improvements in sheet-metal hanging-tools, and has for its objects to providemeans for flanging the edge of sheet metal without the liability to breakage incident to the use of the tools now known, to iiange the metal to the desired angle by one continuous operation, and to provide a strong, durable, and simple construe tion for the tool by which these objects are attained.

Crimping-tools for turning the edge of sheet metal have been heretofore subject to many difiiculties, some of which are as follows: By bending the metal to an abrupt angle the metal is broken at the angle. Vhere the sharpened corners of the ends of the tool come in contact with the metal there is great liability of puncturing the metal at that point. To partially'avoid the first of these difficulties, the metal is gone over two or three times, at each time bending it to a more acute angle, thus adding greatly to the labor. Iobviate these difficulties by means of the tool illus trated in the accompanying drawings, in which-- Figure l is a perspective view of my invention. Fig. 8 is a plan View showing the angles between the two parts of the tool. Fig. 2 is an end view of the tool.

In the drawings, A A are the handles, pivoted near the lower end, where the elongated Hanging blades B B are attached. These Hanging-blades are elongated, and have rounded corners at either extremity, to prevent the cutting of the metal, as in the ordinary tools. These blades have co-operating portions eX- tending from the lower edge upward in different planes of the center, converging gradually to meetwithout forming any sharp corners at the junction. At the points where the curves thus meet the metal is made heavy, to receive the handle, and at the same time to'strengthen the blades at that point. At intervals upon The operation of my invention is: The operator grasps the handles and opens the blades enough to receive the metal against the stops.

The metal beingthus in the grasp of the blades, the handles are operated to close the blades, and then elevated to an upright position, bending the metal to an obtuse angle. The blades are now opened,and the blades carried forward half their length for another grasp. Vhen in this position the blades are again closed, bringing the forward section to the same angle as that j ust passed, while the rear section,which was partially bent by the iirst operation, is bent to an acute and the desired angle; so on down the entire length of the sheet of metal, bending it thus in one opera tion to the desired angle without the liability of breakage, as the metal is brought to the angle gradually. The projections orfingers G C are gages to regulate the width of the flange or crimped portion as they rest on the metal before the jaws are closed.

I am aware that iangingtools have been made with straight blades, and having gages substantially the same as those used in this iiangingtool, and I do not claim such.

N hat I claim is-M 1. A flangingtool for sheet metal, provided with corresponding jaws having two or more co-operating portions extending from the lower edge upward in different planes, substantially as set forth.

2. A flangingtool for sheet metal, provided with corresponding jaws having two or more co-operating portions extending from the lower edge upward in different planes, said jaws being re-eni'orccd where the handles are joined to them, substantially as set forth.

3. A Hanging-tool for sheet metal, provided with corresponding jawshaving two co-operating portions extending from the lower edge IOG upward in different planes, said jaws loeing` In testimony whereof have hereunto set re-enforced where the handles are joined to .my hand, this 29th day of April, A.

with perforations to receive the said fingers, C. W. MURDOCK,

substantially as set forth. J. A. KIGHT.
